# Script used to update the Graphite2 library in the mozilla source tree

# This script lives in gfx/graphite2, along with the library source,
# but must be run from the top level of the mozilla-central tree.

# It expects to find a checkout of the graphite2 tree in a directory "graphitedev"
# alongside the current mozilla tree that is to be updated.
# Expect error messages from the copy commands if this is not found!

# copy the source and headers
cp -R ../graphitedev/src/* gfx/graphite2/src
cp ../graphitedev/include/graphite2/* gfx/graphite2/include/graphite2

# record the upstream changeset that was used
